What Causes Deep Vein Thrombosis While Travelling?
Travelling can be an exciting and enriching experience, but it often involves long periods of sitting, whether in a car, plane, or train. Prolonged periods of immobility can increase the risk of developing deep vein thrombosis (DVT) while travelling, a condition where blood clots form in the deep veins of the legs. To ensure your travels are safe and enjoyable, it’s crucial to understand how to prevent DVT while on the move. In this article, we will explore effective strategies to avoid deep vein thrombosis while travelling and maintain good vascular health during your journeys.
What is Deep Vein Thrombosis?
Deep Vein Thrombosis occurs when a blood clot forms in one of the deep veins, usually in the legs. If left untreated, a clot can break loose and travel to the lungs, causing a potentially life-threatening condition known as a pulmonary embolism. DVT is more common in people who have risk factors such as a personal or family history of blood clots, obesity, pregnancy, or certain medical conditions. However, it can affect anyone, especially during extended periods of immobility, like those experienced during long-distance travel.
Preventing DVT While Travelling
1. Stay Hydrated
Proper hydration is essential to prevent DVT. Dehydration can make your blood thicker and more prone to clotting. Drink water regularly during your journey, and limit caffeine and alcohol, which can contribute to dehydration.
2. Move Frequently
One of the most effective ways to prevent DVT is to keep your blood flowing. If you’re traveling by plane, get up and walk around the cabin every 1-2 hours. In a car, take regular breaks and stretch your legs. On a train, make use of the available space to move around. Simple ankle and leg exercises can also help keep your circulation active while seated. When I am on a plane, I prefer to seat myself inside the plane – so that I have access to an aisle. From there, I am able to stand up as I please and do some stretches and calf-raises – plus I can get to the bathroom more easily!
3. Consider Compression Stockings
Compression stockings are designed to improve blood flow in the legs. They provide graduated pressure, with the most pressure at the ankle, gradually decreasing towards the knee. Wearing compression stockings during your journey can significantly reduce the risk of DVT.
4. Choose Aisle Seats
When booking your flight or train seat, opt for an aisle seat. This allows you to get up and move without disturbing other passengers. On a plane, aisle seats also make it easier to perform in-seat exercises.
5. In-Seat Exercises
In-seat exercises can help maintain blood flow in your legs. Rotate your ankles, flex your feet, and perform knee lifts while seated. These movements encourage circulation and prevent blood from pooling in your leg veins.
6. Elevate Your Legs
When you have the opportunity, elevate your legs slightly, either by resting them on the back of the seat in front of you (on a plane or train) or by using a footrest in a car. Elevating your legs can reduce the pressure on your veins and help blood return to the heart.
7. Wear Loose, Comfortable Clothing
Avoid tight clothing that constricts blood flow, especially around your waist and legs. Opting for loose, comfortable clothing, allows for better circulation.
8. Medication and Consultation
For individuals with a history of blood clots or other risk factors, it’s essential to consult a healthcare professional before travelling. They may recommend blood-thinning medication (such as aspirin or Warfarin) or other preventive measures, especially for long journeys. Personally, I take an enteric coated aspirin every time I fly. It’s effects are minimal, yet it may just stack the deck in my favour and help me to avoid deep vein thrombosis while travelling!
9. Avoid Crossing Your Legs
Crossing your legs for extended periods can restrict blood flow. Try to keep your feet flat on the floor when seated.
10. Stay Informed
Knowing the risk factors and symptoms of DVT is crucial. Be aware of symptoms such as leg pain, swelling, warmth, or redness, and seek medical attention if you experience any of these during or after your trip.
Conclusion
In order to avoid deep vein thrombosis while travelling is essential for your health and well-being. By staying hydrated, moving frequently, wearing compression stockings, choosing aisle seats, and practicing in-seat exercises, you can significantly reduce your risk of developing blood clots during your journeys. Remember that DVT can affect anyone, and it’s important to be proactive in protecting your vascular health while travelling. Always consult a healthcare professional if you have concerns or specific risk factors for DVT, and enjoy your travels with peace of mind.
